Fazio Londe syndrome, also known as progressive bulbar paralysis (or palsy) of childhood, is an inherited motor neuron disease found in children.[1] This condition is characterized by facial weakness, dysphagia, stridor, dysarthria, and paralysis of the eye muscles.[2] There is evidence that there are at least three distinct subtypes: a very rare autosomal dominant form and two variants with probable autosomal recessive inheritance either with early onset of respiratory symptoms and rapid progression to death or later onset, less prominent respiratory symptoms and lengthy clinical course.[1]

The disorder may become generalized leading to paralysis, amyotrophy and abnormally sharp osteotendinous reflexes.[3][4] Median survival for patients with Fazio Londe syndrome is 18 months.[4]

How is Fazio Londe syndrome inherited?

There is evidence that there are at least three distinct subtypes of Fazio Londe syndrome: a very rare autosomal dominant form and two variants with probable autosomal recessive inheritance either with early onset of respiratory symptoms and rapid progression to death or later onset, less prominent respiratory symptoms and protracted clinical course.[1]
